Tool risk reduction measures

100 RISK REDUCTION MEASURES

Please note:

This catalogue contains 100 measures that can contribute to the mitigation of heavy rain risks. These measures are very diverse: they range from structural to non-structural measures and from small, easy-to-implement solutions to comprehensive conceptual approaches.

The catalogue was compiled from existing catalogues from all RAINMAN partner countries as well as from knowledge and experiences made in the project without claiming universal coverage and without having expert knowledge in each of the covered business areas. Sources for further information and good practice examples are provided for a large number of the included measures.

Use the selection feature to find measures that are applicable in the field of action that you are dealing with or search for key words you are looking for.

Please consider that heavy rain risk reduction measures work best, when they are strategically applied and cleverly combined under consideration of the local conditions. Go back to RISK REDUCTION MEASURES for further guidance.

Restoration of floodplains and floodplain forests, natural succession

Identifying and re-establishing of flood plains and deposition areas, such as by removal of protection structures for agricultural land, contributes to the retention of water along rivers and, thus, to heavy rain risk reduction. In the past, most floodplains have been taken over for other uses; former floodplain forests are separated from river and runoff pathways and modified into residual low-density forests without natural regeneration. Land use of flood plains can be different. Most space is required by self-regenerating floodplain forests (“mobile ecosystems”) – much more than floodplain grassland or reed beds. Restoration of such forests is a demanding and long-lasting process and requires planning; however, it is a crucial measure for climate change adaptation and mitigation.

Fields of action
Watercourses, Settlement areas, Forests, Farmland
Additionally to flood risk reduction by slowing and storing surface runoff, the measure has medium or high possible benefits for the following biophysical impacts and ecosystem services: Reduce erosion and/or sediment delivery; Create riparian habitat; Biodiversity preservation; Reduce pollutant sources; Intercept pollution pathways; Create aquatic habitat; Reduce peak temperature; Filtration of pollutants
